Dr. Erwin is co-founder of the Witness Project, a breast cancer education and screening intervention for African American women. The Witness Project, developed in rural Arkansas, has been replicated nationally at more than 30 program sites in 22 states. Since 2001, Dr. Erwin’s ethnographic research has expanded to include the growing Latino/Hispanic population in the U.S. She has investigated and published on the efficacy of the culturally tailored intervention, Esperanza y Vida (Hope and Life) to increase breast and cervical cancer screening in Latinas/Hispanics in Arkansas and New York and is currently funded (R01 CA 171935) to investigate the efficacy of a community-based intervention to increase colorectal cancer screening with African American men and women in Buffalo and New York, NY. Most recently, Dr. Erwin is investigating the effectiveness of social media and breast cancer risk reduction messages to increase positive intent to breast feed by African American mothers (NIH 1R21CA202263) as an important translational study of research at Roswell Park. Dr. Erwin’s research has been funded by the American Cancer Society, National Cancer Institute, Susan G. Komen for the Cure, Centers for Disease Control and Prevention and the U.S. Department of Defense.
